That Time I Got Reincarnated as a Slime Crowned 2026’s Top Isekai

Halfway through 2026, the anime world has already churned out a handful of standout titles, but none have grabbed the isekai spotlight quite like That Time I Got Reincarnated as a Slime. When PR Times released its ebook‑sales ranking for the first six months of the year, the series topped the “isekai” category, edging out fan‑favorites such as Re:Zero and Sword Art Online.

The numbers are impressive: after topping 40 million copies sold by February 2023, the manga kept climbing. Volume 31, which hit shelves in February, moved more than 345,000 copies in just May, a testament to the franchise’s growing momentum.

For newcomers, the premise is simple yet oddly comforting. Satoru Mikami, a 37‑year‑old corporate worker, meets an untimely end, only to be reborn as a sentient slime in a mysterious cave. With a voice‑like AI guiding him, he discovers the ability to absorb anything and inherit its form and powers. Renamed Rimuru Tempest after befriending a loyal beast, he embarks on a grand quest to build a utopia—while unintentionally reshaping the world around him.

Fans aren’t just watching the manga; the anime is in the thick of its longest season yet. Season 4, slated to span five full cours over the next couple of years, has already delivered high‑stakes drama. Early episodes dive into the scheming of Maribel Rozzo, a shadowy antagonist wielding “Greed” powers. After a tense showdown where she tries to dominate Rimuru, the slime emerges stronger, setting the stage for even bigger confrontations hinted at in the latest trailer.

So whether you’re a longtime slime enthusiast or someone just curious about the hype, the data says it loud and clear: That Time I Got Reincarnated as a Slime is the isekai you can’t ignore this year.
